Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Locate the master cylinder reservoir under the hood.
If the fluid is low, refill it with the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
Inspect for any signs of leaks around the reservoir cap.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, wrench
Start with the wheel farthest from the master cylinder (usually the rear passenger side):
1. Attach the clear tubing to the bleeder screw on the brake caliper.
2. Have an assistant pump the brake pedal several times, then hold it down.
3. Open the bleeder screw to release air and old brake fluid; close the screw before the assistant releases the pedal.
4. Repeat until clear fluid is seen, then move to the next wheel (rear driver side, front passenger side, front driver side).
Ensure the brake fluid level remains above the minimum mark during the process.

4. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench
Inspect brake pads for thickness; replace if worn below 3mm.
Check rotors for scoring or warping; replace if necessary.
Use a torque wrench to tighten caliper bolts to the manufacturer’s specified torque values.

5. Test Brake Booster

Tools Required: Vacuum gauge (if necessary)
With the engine running, press the brake pedal several times to deplete the vacuum in the booster.
The pedal should feel firm after a few presses. If it remains soft, the brake booster may be faulty and should be replaced.
